Chapter 2 Command Codes
The format for the form definition program sent from the host computer is as
follows:
1. The EVFU Start Load code (^>) is sent first. The Code V must be in the
Graphics Mode to load and use the EVFU in the Graphics Mode.
2. The Channel 2 code (^1) is sent twice to assign the first two lines of the
form as fillers. Filler lines are not called by the print program. The same
channel code can be used to assign all filler lines of the form.
3. The Channel 1 code (^0), which is the top-of-form (TOF) code, is sent to
assign form line number 3. This is the first line of the form with print data.
In the sample form, this line is used for company name information.
(Alternately, the TOF code could be assigned to the first line of the form
and a unique channel code assigned to line 3.)
4. The Channel 2 code is again sent four times to assign line numbers 4
through 7 as fillers.
5. The Channel 3 code (^2) is sent to assign line number 8. In the sample
form, this line is used for item information.
6. The Channel 2 code is sent to assign line number 9 as a filler.
7. The Channel 4 code (^3) is sent to assign line number 10. In the sample
form, this line is used for color information.
8. The Channel 2 code is sent twice to assign line numbers 11 and 12 as
fillers.
9. The Channel 5 code (^4) is sent to assign line number 13. In the sample
form, this line is used for quantity information.
10. The Channel 2 code is sent twice to assign line numbers 14 and 15 as
fillers.
11. The Channel 6 code (^5) is sent to assign line number 16. In the sample
form, this line is used for purchase order number information.
12. The Channel 2 code is sent twice to assign line numbers 17 and 18 as
fillers.
13. The Channel 7 code (^6) is sent to assign line number 19. In the sample
form, this line is used for date information.
14. The Channel 2 code is sent to assign line number 20 as a filler.
15. The EVFU End Load code (^?) is sent last to terminate the memory load
routine.
After the EVFU is loaded, sending one of the EVFU codes in the data stream
(or as a line terminator) causes the printer to slew the paper to the line
assigned to the EVFU code sent.
